When I bought this Willy's, it did not have a body tag. The previous owner told me it was a CJ3a. It appears to be a CJ3a, but now that I have it running and driving, i'm getting ready to get it titled and I want to be 100% sure. I also want to get a reproduction body tag to put back on. Also, every one says there is a serial # on the frame, but I have not been able to locate to. Any ideas where I should be looking? Thanks in advance.
